There's a new room on the International Space Station. NASA inflated it Saturday. The Bigelow Expandable Activity Module (BEAM) was filled with air by astronaut Jeff Williams as the ISS flew over the south Pacific, kicking off an experiment to learn how inflatable habitats perform in a microgravity environment. "I think I am the first amateur astronomer to photograph BEAM from Earth," says Philip Smith, who sends these before-and-after images from Manorville, New York:

"Using a backyard telescope, I tracked the ISS as it passed overhead on May 26th (before inflation) and May 28th (after)," says Smith. "The new addition was clearly visible in my images."

"The Bigelow Aerospace-built BEAM is a prototype space habitat for future space stations, moon colonies and moon bases," he adds. "I am glad to be a small part of that history."BEAM will remain attached to station for a two-year test period. Astronauts will not occupy the new room, but they will enter from time to time and monitor its performance. For more information about BEAM, visit: www.nasa.gov/beam. ﻿www.spaceweather.com﻿
